PCI & AGP: Local Bus Programming and Info

PCI Information has some great information for PCI bus developersand it’s free (according to the site’s author, “This is information that you CANNOT get for free from the PCI SIG; they want to charge you exorbitant amounts of money for the information”). PCI Information opens with a technology backgrounder on the PCI bus and slots, along with some early (circa 1998) programming notes. But the most valuable section of the site is a still-updated list of more than 4,500 PCI vendor and device codes. In addition, you’ll find several free utilities, including one that checks the vendor and device date you’ve entered and “looks for formatting errors, wrongly keyed hex-bytes, invalid tags, truncated lines and the like.” Another utility turns the vendor and device-code database into binary type files, ready to link directly into programs. The site also offers an impressively comprehensive list (8MB in ASCII format) of PCI interrupt calls, I/O ports, memory locations, far-call interfaces, and more. Bottom line is, if you’re a PCI developer, this site’s a great one to bookmark.
